Biorad PowerPac Basic Electrophoresis Power Supply
- Programming in a compact, stackable case
- Timer control and constant voltage or constant current output
- Ability to pause and resume a run
- Automatic crossover featured to prevent damage
- When the set limit of the non-constant parameter is reached, and the power capability of the unit is not exceeded
- Used for nucleic acid gel electrophoresis & protein gel electrophoresis
The PowerPac Basic provides constant voltage or constant current to instruments used in
electrophoresis. The power supply operates at the values specified for the constant parameter. However, to prevent damage to the electrophoresis cell, the PowerPac Basic provides automatic crossover to constant current or constant voltage, depending on which set value is first reached. When the set limit of the non-constant parameter is reached, and the power capability of the unit is not exceeded, the power supply will switch, making the non-constant parameter the new constant parameter
All of our equipment is fully tested to perform at factory specifications before being shipped.
The Biorad PowerPac Basic Electrophoresis Power Supply includes:
- > Power Cord
- > Calibration
- > Operator's Guide
- > Full 180 Day Parts and Labor Warranty
